bigbuck08 Posted October 6, 2007 Share Posted October 6, 2007 I found a list of settings for the memory I am using, but am not sure if they will work with my motherboard. Testing parameters for Twinx/XMS2-6400C3DF: Twin2x2048-6400C3DF Data Sheet Motherboard make and model: Asus M2N32-SLI Premium/Deluxe Each pair is tested and packaged together using the following settings: AI Over Clock Tuner: Manual CPU External Frequency: Manually set to 200MHz DDR2 SDRAM Clock: Manually set to 800MHz PCI Express Freq: Auto PCI Freq: 33.33 Performance Mode: Standard DRAM Timing Selectable: Manual SDRAM CAS Latency: 3T SDRAM RAS to CAS Delay (tRCD): 4T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 9T SDRAM Write Recovery Time: 5 Command Rate: 2T DDR2 SDRAM Voltage: 2.4 V CPU Core Voltage: Auto FSB Termination V: 1.50 V MCH Chipset V: 1.65V ICH Chipset V: 1.20V M2N32-SLI ADVANCED Voltage Control: CPU Vcore offset:-Disabled DDR2 Termination:-0.5X CPU to NB HT:_____1.200V NB to SB HT:______Auto NB Core/PCI-E:____Auto SB Core/PCI-E:____Auto SB Standby core:__+1.500V All other settings are motherboard defaults. Maximum DDR2 recommended VDIMM: 2.2 Volts Will these settings work with the motherboard listed in the title? Also, are some of these settings different on different motherboards as I do not see some of the settings listed in my BIOS. Link to comment Share on other sites More sharing options...
DerekT Posted October 6, 2007 Share Posted October 6, 2007 Please post the CPU you are using with the P5N32-Sli Plus motherboard. For example, an E6850 and 6400C3DF: Multiplier = 9 FSB = 266 DRAM = Unlinked and set to 800Mhz (PC6400) ie: Memory Timing FSB - Memory Clock Mode: Unlinked CPU FSB: 266 CPU Multi: 9 DDR FSB: 800 tCL: 4 tRCD: 4 tRP: 4 tRAS: 10 Advanced Memory Settings tRRD: Auto tRC: Auto tWR: Auto tWTR: Auto tREF: Auto Async Latency: Auto CMD: 2T CPU Spread Spectrum: Disabled PCIE Spread Spectrum: Disabled MCP PCIE Spread Spectrum: Disabled SATA Spread Spectrum: Disabled LDT Spread Spectrum: Disabled CPU Internal Thermal Control: Enabled Limit CPUID MaxVal: Enabled Enhanced C1 (C1E): Enabled Execute Disable Bit: Enabled Virtualization Technology: Enabled Enhanced Intel Speedstep Tech: Enabled LDT Frequency: 5x PCIEX16_1 Frequency (Mhz): 101 PCIEX16_2 Frequency (Mhz): 101 PCIEX16_3 Frequency (Mhz): 101 SPP<->MCP Ref Clock, Mhz: 201 -- Voltages -- Vcore = Auto Vdimm (DRAM Voltage) = 2.25v 1.2v HT: Auto NB Vcore: Auto SB Vcore: Auto CPU VTT: Auto Link to comment Share on other sites More sharing options...
bigbuck08 Posted October 6, 2007 Author Share Posted October 6, 2007 I am using an E6600 2.4Ghz. I havent overclocked and am not sure if I plan on doing so. Link to comment Share on other sites More sharing options...
DerekT Posted October 6, 2007 Share Posted October 6, 2007 Please post your FPO/Batch number. It will be on the box. Link to comment Share on other sites More sharing options...
bigbuck08 Posted October 6, 2007 Author Share Posted October 6, 2007 I dont have the boxes anymore. Would it be in the manual somewhere? Link to comment Share on other sites More sharing options...
DerekT Posted October 6, 2007 Share Posted October 6, 2007 I have edited the settings (Above) for your processor and Twin2X 6400C3 DRAM. Link to comment Share on other sites More sharing options...

DerekT Posted October 6, 2007 Share Posted October 6, 2007 No problem. Please let me know how it works out. Please download memtest from http://www.memtest.org and burn the image to an optical disk. Boot from the disk and let it run a few passes. VERY nice DRAM by the way... Results? Link to comment Share on other sites More sharing options...
bigbuck08 Posted October 6, 2007 Author Share Posted October 6, 2007 I just noticed, wouldnt the timing be 3-4-3-9 as shown in the specifications of Twin2X 6400C3DF? Also, I couldnt get Memtest to boot but will try again. Im using Vista 64bit so am not sure if that is a problem or not. EDIT: Just noticed something else. For the CPU FSB you put 266 but mine is set at 1066. Wouldnt that be running it way lower? Link to comment Share on other sites More sharing options...

For the CPU FSB you put 266 but mine is set at 1066. Wouldnt that be running it way lower? First test with 4-4-4-10. Let's find stability on your system. 266 x 4 (Quad Pumped) is 1066Mhz. You need to boot to the CD. Enter your BIOS and set the system to boot from the CD. You did burn the CD as an Image from the ISO? Link to comment Share on other sites More sharing options...
bigbuck08 Posted October 6, 2007 Author Share Posted October 6, 2007 I burnt it to the disc incorrectly. :(: Am downloading Nero now to burn it right this time. I will set the timings back to what you gave and let you know what happens. If you dont mind, do you have MSN or similar? I really appreciate your help.

bigbuck08 Posted October 7, 2007 Author Share Posted October 7, 2007 Memtest was good with the 4-4-4-10 timings so I put them to 3-4-3-9 like you said. Let it run once and Memtest came with a few errors and at the end said Bad Memory DIMM B1. Seeing as the memory was fine for two passes with the higher timing does that just mean it needs to be modified more for the lower timing or the RAM is actually bad? Edit: I raised the Voltage to 2.4V and ran Memtest for one pass and there were no errors! Looks like it will run good like this now. I have another question though. Will these settings be different with 4GB of this RAM? I plan on buying another 2GB, total 4GB, late this month or next. Link to comment Share on other sites More sharing options...
DerekT Posted October 7, 2007 Share Posted October 7, 2007 Good work. Yes, that's the default voltage for those timings. Yes, if you attempt to install two more GB of this DRAM, you will, very likely, lose bandwidth and possibly timings. It's just not worth the problems that very likely will arise.

bigbuck08 Posted October 7, 2007 Author Share Posted October 7, 2007 Let me see if I understand this correctly. By installing more memory, which to my understanding would make things run faster, I would actually lose speed? Link to comment Share on other sites More sharing options...
DerekT Posted October 7, 2007 Share Posted October 7, 2007 Let me see if I understand this correctly. By installing more memory, which to my understanding would make things run faster, I would actually lose speed? You will gain the ability to use more DRAM for capacity purposes. DRAM is faster than swapping to the hard drive. However, in instances where less than 2GB is necessary, and that is a major portion of usual computer use, the system will run slower because the read/write is slower. The memory controller can not keep up with the extra DRAM at the full rated speed. You will need to drop the speed of the DRAM a speed level ie. 1066Mhz to 800Mhz, 800Mhz to 667Mhz, 667Mhz to 533Mhz. Think of it this way. If you have a small phone book, then when you go into the index to find the page where you will find the phone number you are doing so at a certain speed due to the pages of the Index. Then you have to drive through the pages to get to the number. Now if your index is twice as large and the pages twice as many, then it takes longer to access the data. Now DRAM has a Strobe and the length of the strobe is how long the rows and columns can be left open before they must be refreshed. There is not enough time for the dram to be refreshed and then accessed with 4GB at the full access speed of the DRAM. The chipsets are optimized for 2GB, not 4GB and for 2 DRAM slots, not 4 DRAM slots populated. You can overclock the FSB (and hence the Memory Controller Hub = MCH) to gain some extra bandwidth and thus access the capabilities of the DRAM since the chipset is now clocked up. Usually when you clock up the FSB and concurrently the Memory Controller Hub (MCH) you need to raise the voltages of the CPU/MCH a bit as well.

bigbuck08 Posted October 7, 2007 Author Share Posted October 7, 2007 I think I understand this now. The analogy helped :). I want to OC my CPU anyway. I ordered a CPU cooler which should be here Wednesday. Ill make a post in the Enthusiast section. Link to comment Share on other sites More sharing options...
